Interference in blood tests may cause falsely high or low results, potentially leading to misdiagnosis or erroneous treatment. Such interference may be related to antibodies or proteins in the blood, as well as medications, supplements, or sample handling. While some types of interference are detected automatically by laboratory systems, others remain unrecognised in routine practice. Clinicians should consider interference when laboratory results do not align with the clinical presentation or related test results and involve the laboratory to ensure correct interpretation, as argued in this review.
